' 16 claims. (C1. S12- 155) This invention introduces a combination. in which at least two hingedply associated members, both pivotally associatedwith a'third member, can, in association with a Scam and follower member, act coordinately in predeterminedspecial relationships to each other.

This combination may be further described as embodying a cam hinge device `comprising threer members. One of the three is a connecting or base member, two of them, associated with each other in a cam and follower relationship, are inde-v pendently associated in a pivotal relationship with the third, but coactively coupled by means of an element which keeps them securely together. The device is so uniquely developed that: the element coupling the twomembers serves also as.

the follower element in the cam and follower.

relationship.

A useful application ofthe present combina- A( tion is disclosed in the present application. in connection with a poker chipholde'r of the type. shown in my Patent No. 2,196,818. In this connection, the cam hinge serves not only to pivotally connect sections of the poker chip holderibut-also to control and actuatek oneof them asa retain-` ing means for the contents of another section.

The construction and variousfunctions of this.; device will appear more clearly from a studyof the accompanying drawingswhich 4aremadeapart of this specification, terminatingin a set of claims. v I

Figure 8 shows the right hand side of the unit with the containers a and the retainers s in diner- ;cn line II-II of Figure 9.

In the drawings'as detailed delineations the numeral I indicates a housing comprising a poker chip holder, as a whole, which is included in this application to disclose the mechanical combination conventionallydened in the appended claims. This housingA I accommodates oneach side of it a box-like container 3 accommodating therein several stacks of chips I3. Each container 3 includes a wall'28 forming one side 0f the housing I and the narrow walls 29 and 30 at right angles to wall 28 (see Fig. 1).

The housingv is divided by axis A to indicate right R. and left L half in the unit. The two being symmetrical, an explanation of one half is constructively an explanation of the other half.

The housing I has two end walls indicated by thenumeral I5, a. bottom Wall indicatedV by the numeral I'I, and a top wall divided into convex sections I6. When the box-like containers are turned into the housing I, the-unit looks like two volumes of books, which 'simulation yields itself to enhancement by leather covering or the like.

The mechanical combination primarily disclosed herein is the device which makes possible the'movement of the container 3, into and out of the housing I without spillage of contents I3.

The housing I (see Figs; 1, "l and 8) is generally of rectangular structure openr on two sides and with the includedl containers 3, is a typical Y framework `ofwalls vin'which two hinge com- The housing comprises two symmetrical halves L'and R. The two hinge combinations Aare similar except that one is a right hand and one is a left hand hinge combination and therefore a description of one hinge combination'will suflice for the present specification,

1especially since it is not the purpose to limit the application of the hinge combination to such use.

Associated with each container 3 is a wall 6 which, whenl the container is contained within the housing,'extends parallel with the container and Vis spaced from the open side thereof far enough to leave room for a stack of poker chips or other articles between the wall 28 of the container and the wall 6. In the operation of the hinge combination the wall 6 remains parallel with the wall 28 during part of the time that the 'container is being swung out of the housing so as to prevent spillage of the chips (see dotted lines lin Fig. 8) and subsequently thewall 6 is moved back into-its former -uprig-ht position.vr

Each hinge combination comprises three memwall G into parallel relation with the tray, after' which-the tray and wall move back into upright position.

From theabove it is apparent that the wall 6 functions to prevent'the contents ofthe tray from spilling out therefrom during the interval that Lthe 4traycis approaching... or ,receding ,from its upright; positiom' 1 The invention outlined herein is ofcourse susbers, namely a hinge plate 4 which is fastened to .1Q.,.ceptible to Various changes and modifications, the
